CreateControlInterface Failed in SAP Management console

Nov 05, 2013 at 03:54 PM|13 Views

Hello,

I am trying to perform a Netweaver 7.4 install on Suse Linux and getting an error. The install finishes without issue and everything looks fine and dandy. But when I try to start the SAP Management Console I get an error saying CreateControlInterface failed. I googled around but couldn't find a resolution to the problem. This is the error:

java.lang.NullPointerException

JRE 7u40 fixed the issue for me as well. Apparently this is a common issue. Oracle has started to enforce certain security practices that were started with JRE 7's release. Now that they are enforced, everyone is scrambling to update their code.

The fix is to download the latest 720 kernel version of the SAPMC. I have a 721_EXT Kernel installed and it seems that even updating to the latest SAPMC library from that kernel does not fix the issue... you will need to go to http://service.sap.com/swdc --> Support Packages and Patches --> Browse our Download Catalog --> Additional Components --> SAP Kernel --> SAP KERNEL 64-BIT UNICODE --> SAP KERNEL 7.20 64-BIT UNICODE. Select your operating system and then choose Database Independent. Download the "sapmc_516" SAR file and then update your SAP Kernel accordingly.

After restarting your system, you should be able to use the SAP MC again without any issues.

This is very new and unique error you are getting. I looked up and found some additional details like if your IP and FQDN entries are maintained in hosts file. Also if your hostcontrol is updated or not.
